Toall whom t may concern:

Be it known that I, AN'roN SWANsoN, a

citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and use-v f'ul Improvements in Motor-Cycles, of which the following is a specicatlon.

My invention relates to improvements in bicycles and more specifically tothe motordriven or motorcycle type thereof. The object of my invention is the provision in a bicycle of the character mentioned of means whereby the same may be supported in an upright position When inert.

A further object is the provision in conjunction Wit'h the operating means of the supporting means mentioned of operative connection between said operating means and the engine clutch and the bicycle brake whereby, actuating said ope-rating means to operatively position said supportingy means will effect the application of the brake and the gradual opening of the clutch and vice versa When said operating means are;` thrown to inoperatively position said supporting means.

A further object is the provision in a motorcycle of improvements as mentioned which. will be of durable and economical construction and etlicient in operation.

Other objects will appear hereinafter.

With these objects in view my invention consists in improvements in a. motorcycle characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter fully described and more particularly pointed out in tlw appended claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side view of a motorcycle in which is embodied the preferred form of my invention, Fig. 2 is a vert-ical transverse section taken on substantially lille -m of Fig. 1, Fig.` 3 is an enlarged detail elevation of the power shaft of the engine, shown in Fig. 1, and certain parts coacting therewith, Fig. 4 is a top plan view thereof, and Fig. 5 is a section taken of Fig. 4.

Referring now to the drawings 1 designates the frame of the bicycle, 2 2 the frontk and rear wheels respectively thereof j which are mounted upon the shafts 3-3'.'

respectively.

4 indicates the is suitably monnte the' power shaft of said engine. mounted upon the shaft 5 between ing collars 6 sprocket wheel 7. Connecting said s rocket and a larger sprocket 8 keyed or oter'wise secured 'to the shaft 3 is a s rocket chain 9. Formed upon one side o the sprocket wheel 7 is a female cone-clutch part 10. Splined to the shaft 6 isthe part 11 arranged and designed, as shown, for cooperation with said female clutch part 10. Fulcrumed at 12 to the up er end of a stationary arm 13, the lower end) of `the latter being 'rigidly secured as itt/14 to a. stationary art. of the structure, is a fork the lower bifurcated end of which is operatively connected by means of studs 16 with the clutch member 11, said studs engaging a circumferential 'groove 17 in the periphery of said clutch member. A compression spring `18 interposed between the clutch members and 11 is adapted to normally hold the same in open or disengaged positions. the operative interlocking or closing of said clutch parts being brought about by outward rocking of the upper end 19 of the fork. Thus the operative connection between the propelling engine and the sprocket wheel 7. and hence between said engine and the wheel 2 is effected.

Having their `upper extremities secured to the respectivei ends of a rock shaft 20 mounted 1n and extending through the shaft 3 are depending forks 21 in the' lower end of each of whichis mounte a. wheel 22. The arrangement is such'tt at when said forks are 1n depending vertical positions, the wheels 22 will contact the ground and elevate the wheel 2'V from the latter, as clearly shown in Figs- 1 and 2, contact of the wheel 2 with the ground being ermitted only when said vforks are tilte `rearwardly, in which event the wheels 22 will evidently be elevated from contact with the ground. t B

Fulcrumed `at 23 to the bicycle frame 1 ro ellin en 'ne whicld iii) the lramge1 l, and .'5

Loosely'" positon` pinned to the latter, is V"ai" male clutchv sli` is a lever 24 the upper end of which prol jects, as shown, in the bicycle saddle. rovided upon the upper portion of the frame `1 is an 4angular .plate A25 the-proiectinggllange parte-26 of olerative proximity with loosely, enga 'ng which is notched 'as at 27 and 28 for engagement by the lever 24, whereby the latter may be held in either operative or inf operative position. Connecting lthe lower end of said lever and one of the forks 21 is a link 29. With this arrangement it`will be seen that u on the rearward tilting of said lever, which vtilting effects the forward drawing of the link 29, the wheels 22 will be lowered to operative position; and that upon the reverse operation of said lever, said wheels will be elevated to inoperative osition, in either of which positions said lever maybe held by engagement with the notches 27 or 28.

. Arranged upon the outer side of the link v29 is a projecting curved stra tioned, to engage the stem 19 of the fork to cause the rocking of the latter to operative position.

' Encircling the sprocket wheel 7, more precisely the clutch-part forming portion 1') thereof, the same resting int a c1rcumferential channel 31 provided in the periphery thereof is a friction strap 32 adapted to constitute a brake. The respective ends of said strap are. connected, as clearly shown in Fig. 3, by links -33 and 34 with a pin 35 an'elongated slot 36 provided in the vin 29. In order to crmit of adjustment of the strap 32 a out the sprocket 7, the link 34 is formed in two parts, which arts are connected by a turnbuckle 37. T e'connection between the link 29 and the strap32 is such that upon the forward reciprocation of the former the latter will be drawn by said link tightly around i. the sprocket? to effect the braking thereof and hence of the rear wheel of the bicycle;

and that when said link is at its rear posiv tion relaxation of'said strap will be permit- 4s ted. Hence, with the arrangement set forth, provision is made in the form of wheels 32 lfor the positive support of the bicycle when inoperative, the operating lever 24 of said sup orting wheels being so connected with thelb icycle brake'and clutch that when said lever is thrown to operative position, relative to the supporting wheels, said clutch will simultaneously be thrown out and said A` brake thrown into o erative en a ement.l

Th P g g 'is constructiontherefore presents an arrangement whereby the ordinary bicycle l -He automaticall converted into a tricycle at intervals w en other forces which 'aerve to hold the same upright when in mo;

vtion, -eease to so act upon the same.

,While Il have shown what I deem to be the l-fgreferable form of my improvements'I do 'Y' t wishto be limited thereto as there might jvarious changes made in the details vof 'a'hlnstruction and the arrangement of parts described without departing from the spirit of the invention comprehended within the scope of thel appended claims. And al-V though I have shown my improvements as incorporated in a bicycle of a particular design the same may be employed in connection with a bicycle of any other construction to which it is applicable.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a motorcycle comprising a bicycle, a propelling motor carried by the latter, a driving connection between said motor and the rear wheel of said bicycle, and a clutch interposed in said connection,V of a pair of supplemental wheels carried b the frame of said bicycle, said wheels being adapted to be rocked to contact with the ground to su port the bicycle in upright position or to e elevated from engagement therewith, means for operating said wheels, and a connection between said means and said clutch whereby said clutch will be closed when said supplemental wheelsare elevated and opened when said wheels are lowered to contact with the ground, substantially as described.

2. The combination with a motorcycle comprising a bicycle, a propelling motor carried by the latter, a driving connection between said motor and the rear wheel of saidbicycl, a clutch interposed in the connection between said motor and said wheel, and a brake for the clutch for said wheel, of a pair of supplementalnwheels carried by the frame of said bicycle, said wheels being adapted to be rocked to contact with the ground to support the bicycle in upright position or to be elevated from engagement y therewith, means for operating said wheels,

and a connection between said operating means and said clutch and brake whereby said clutch will be closed and said brake relaxed when said wheels are elevated, and whereby said clutch will be opened and said brake operative when said wheels are lowered, substantially as described.
